Lever-type connector

Abstract

A lever-type connector includes a first housing, a second housing, and a lever for moving the second housing. The lever is formed with cam grooves and the second housing includes cam followers movable along the cam grooves. The lever is rotatable about axes of rotation movable within a predetermined range with respect to the first housing. The cam groove includes a first groove portion configured to guide the cam follower, a second groove portion disposed along the first groove portion on the side of the axes of rotation with respect to the first groove portion and configured to guide the cam follower, and a coupling groove extending in a direction intersecting the first and second groove portions to couple the first and second groove portions and configured to guide the cam follower. The coupling groove extends in a direction along a moving direction of the axes of rotation.

What is claimed is: 
     
       1. A lever-type connector, comprising:
 a first housing; 
 a second housing to be connected to the first housing; and 
 a lever for moving the second housing in a connection direction to the first housing by being rotated with respect to the first housing, 
 wherein: 
 the lever is formed with a cam groove and the second housing is formed with a cam follower movable along the cam groove, 
 the lever is rotatable about an axis of rotation movable within a predetermined range with respect to the first housing, 
 the cam groove includes a first groove portion configured to guide the cam follower, a second groove portion disposed along the first groove portion on the axis of rotation side with respect to the first groove portion and configured to guide the cam follower, and a coupling groove extending in a direction intersecting the first and second groove portions to couple the first and second groove portions and configured to guide the cam follower, and 
 the coupling groove extends in a direction along a moving direction of the axis of rotation. 
 
     
     
       2. The lever-type connector of  claim 1 , comprising a coupling portion coupling the first and second groove portions, wherein:
 the first and second groove portions are formed to penetrate through the lever, and 
 the coupling groove is provided on the first housing side of the coupling portion. 
 
     
     
       3. The lever-type connector of  claim 1 , wherein:
 the first housing is formed with a support shaft concentric with the axis of rotation, 
 the lever is formed with a first shaft hole and a second shaft hole, the support shaft being rotatably inserted into the first and second shaft holes, and a partitioning portion partitioning between the first and second shaft holes, and 
 the partitioning portion is deflectable and deformable in a direction to allow a movement of the support shaft between the first and second shaft holes. 
 
     
     
       4. The lever-type connector of  claim 3 , wherein a contact portion for coming into contact with the partitioning portion to deflect and deform the partitioning portion by rotation of the lever projects on an outer periphery of the support shaft.
